Question

我写代码。

函数def中的if语句。

我不知道为什么答案总是“是”

假设我们键入“ n”

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class KOTH_ZoneRandom : MonoBehaviour
{
    int Rand;
    int Length = 4;
    List<int> list = new List<int>();
    void Start()
    {
        list = new List<int>(new int[Length]);

        for (int j = 1; j < Length; j++)
        {
            StartCoroutine(loopDelay());
            Rand = Random.Range(1, 4);

            while (list.Contains(Rand))
            {
                Rand = Random.Range(1, 4);
            }

            list[j] = Rand;
            print(list[j]);
        }

    }
    IEnumerator loopDelay ()
    {

        print("started delay");
        yield return new WaitForSeconds(60);
    }
}

Answer 1

通过不区分大小写，可以简化它

a = input('Yes or No Type [Y/N]')

def test():

    global a

    if a.lower() == 'y': #this will convert the string into lower case

        print("yes")

    elif a.lower() == 'n':

        print("no")

    else:

        print("Not Yes and Not No")

test()

Answer 2

尝试以下方法使其更强大：

yes = ['Y' , 'y' , 'yes' , 'YES', 'Yes']
no = ['N' , 'n' , 'NO', 'No', 'no']

if answer in yes:
    print("yes")

if answer in no:
    print("no")

Answer 3

yes = ['y', 'yes']
no = ['n', 'no']

if answer.lower() in yes:
    print("yes")

if answer.lower() in no:
    print("no")
